Application filed April 20, 1914.. Serial No. 833,206.

ginia, have invented. certain new and useful improvements in Metal Railllies, of which the following'is a s'pecification.

The inventionirelates1 tonew and useful improvements ingil ties and has for one of its objects to provide'aufiimple, durable and inexpensive rail tie{ which employs' novelfastening means 'and'will hold the rails firmly against spreading and creeping and is preferably formed of metal.

Another object of our invention is to urovide a metallic rail tie that is formed of a single piece of metal and is approximately concave convex to provide a certain amount of resiliency and to insure its remaining firm within the road bed.

Another important object of our invention is to provide novel means for securely clamping the rails upon the tie, said means serving to securely hold therails against creeping or spreading and dispensing with the usual spikes; thus eliminating the possibility of the rails working loose incident to the passing of trains thereover.

The above and additional objects are accomplished by such means as are illustrated in the accompanying drawings, described in the following specification and then more particularly pointed out as claimed.

With reference to-the drawings, wherein we have illustrated the preferred embodiment of our invention as it is reduced to practice, and throughout the several views of which similar reference numerals designate corresponding parts, Figure 1 is a plan view showing a rail in place and partly in section with the clamping means at one end of the tie removed. Fig. 2 is a fragmentary longitudinal sectional view, showing onerail in secured position upon the tie. Fig. 3 is a transverse sectional View taken on the plane of line '33 of Fig. 2, and Fig. 4 is a detail perspective view of one of the pins forming a part of the rail clam ing means.

Referring to the drawing by c iaracters of reference the numeral 1 designates our improved rail tie and is formed of a single piece of some suitable metal and is approximately coneavo convex. The ends of the tie are enlarged and partly rounded to provide approximately spoon shaped end portions 2 and 3. These portions 2 and 3 are concavo-convex and may be readily tamped in:

the road bed and providea great bearin surface at points where the most strain an weight is placed upon the tie. The body portion 4 of the tie is provided with inclined side walls 5. This arrangement in combination with the spoon shaped ends v provides for a' firm bearing of the tie upon the road bed and prevents derangement.

We provide rail clamping means adjacent each end of the tie to securely clamp the rails. The rail clamping means comprises a rectangular plate 6 that is suitably secured longitudinally of,the tie adjacent each end thereof and provided at its ends with upstanding flanges 7. Keyhole slots 8 are formed adjacent each end of the plates and are positioned over depressions 9 formed in the upper surface of the tie. Rail clamping members 10 and 11 are mounted ppon each plate' and are designed. to clam opposite sides of the rails 12, as clearly s own in Fig. 2. The rail clamping members 10 and 11 are formed of some suitable'metal and are of suitableangular shape to conform to the shape of the rail and plates upon which they are mounted. To hold the clamping members 10 and 11 in clamping position we.

provide in connection-with each plate upstanding pins 13. The pins 13 are provided with transverse wedge shaped openings 14 adjacent their upper ends and at I their inner ends are recessed upon opposite sides to provide flat faces 15 and a head 16. To place the pins 13 in osition the heads are inserted through the arger parts of the keyhole slots 8 so that the flat faces 15 may be positioned in the shank portions of the slots thereof.- This arrangement prevents turnin of the pins. and the depressions 9 forme in the tie permit the inserting of the pins as described.

The clamping members 10 and 11 are provided with transverse openings '16 extending therethrough from side to side andwhich are arranged to aline with the openings 14' when the pins 13 are in positlon. Vertical openings or recesses 17 are formed in the members 10 and 11 and receive the.

pins 13. The openings or recesses 17 extend-partly through the members 10 and 11 and communicate with the transverse openin s 16.

mall wedge ins 18 are inserted throu h the alined openings 16' and 14 to holdt e clamping members 10 and 11 securely in position. T he smaller ends of the pins 18 project beyond the members 10 and 11 and are preferably struck with a hammer so as to be bent, as at 19, to prevent accidental derangement. lhe under faces of the clamping members 10 and "11 are concaved, as at 20, to enable the ready positioning of the members upon the pins 13. a

It will be readily seen with reference to the foregoing description and accompanying drawings that we provide a novel rail tie and clamping means for rails which will withstand the elements and serve in a reliable and etlicient manner to holdthe rails in position.

in practice, we have found that the form of our invention, illustrated in the drawings and referred to in the above description, as the preferred embodiment, is the most eficient and practical;" yet realizing that the conditions concurrent with the adoption n our device will necessarily vary, we destiny to emphasize the fact that various minor changes in details of construction, propor tion and arrangement of parts may be resorted to, when required, without sacrificing any ,oi' the advantages of our invention, set forth.

Having thus described the invention what is claimed as new, is:

The combination with a rail ti bit clamping means carried by said rail tie and comprising plates having upstanding flanges mounted upon the tie a iacent to the ends thereof, said plates keyhole slots verse openings in the menses formed therein, said tie"having.. depressions formed therein beneath the keyh leslots, upstanding pins having" 'openings" there through 'removably mounted within thekeyhole slots, rail clampingmembers mounted upon said plates engaging the endflanges and provided with transverse openings alining with the openings in said pins, and wedge pins inserted through said openings.

2. The combination with arail-tie, of rail clamping means at each end thereof, said rail clamping means comprising clamping members to clamp opposite sides of rails and having openings formed transversely therethrough and vertical recesses communicating with said openings and opening at the lower sides of the members, upstandingpins carried by the tie having transverse openings adjacent their upper ends, said pins extend ing within said vertical recesses and having the openings therein alining with the transclamping members, wedge pins inserted through the alined openings and being bent at their smaller ends, said upstanding pins having heads on their lower ends and plates to support the clamping members having hey-hole slots therein to receive the pins.

in testimony whereof we aflix onr signd tures in presence oi two witnesses;
